The Craft of Industrial Insulation
The Industrial Insulator’s job involves measuring, cutting and fitting a variety of insulation materials to pipe work, valves, pressure vessels, tanks, ducting, flues, or on any hot or cold surfaces for the purpose of thermal insulation, fireproofing or soundproofing. It also involves the cladding of the insulation material with suitable coverings such as sheet metal, aluzinc, stainless steel or other specified coverings and finishes, such as, felt, cement, various rubbers, canvas and foils.
Metal cladding involves pattern layout and development of sheetmetal (mild steel, galvanised mild steel, stainless steel, aluminium and other alloys) up to 1.2mm and the use of various machines. These patterns would include pipe work, vessels, domed ends, valve and flange boxes, tee pieces, reducers, transformers etc. The patterns are then fabricated by hand and with the aid of machines. They are then joined and assembled using self-securing joints, riveting, fasteners, flanging, swaging and banding suited to the appropriate finishing techniques. Non-metallic finishing may be joined by adhesives, banding or strapping as appropriate.
With the onset of new technology, modern cutting and cladding involves the use of CNC machinery. Planning, costing/estimating, quality control and environmental considerations (energy conservation) are areas in which the Industrial Insulating will operate to ensure cost effectiveness throughout the industry.
